UBIFS FS CHECK

[sim_guo]

On the imx6ul board, when the ubifs error occurs, can i repair the rootfs by fsck ?

Hi gxf

seems not according to linux ubifs documentation

linux/ubifs.txt at master · spotify/linux · GitHub 

some workarounds are suggested on

Force fscheck ubifs - NETGEAR Communities

By default, about 2% of the whole chip size (20/1024 PEB) are reserved for bad blocks handling. If the number of blocks that turn bad exceeds that allocation, an error message will be printed and UBI will switch to read-only mode.

Can I improve the bad block handling size to reduce the possibility of errors?
If I can, what should I do?
